Super excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific “behavioral motifs” absent in naive animals (1/5)

🧠🧪Brain-bending news: A new study reveals how changes in cell behavior and number affect the formation of distinct grooves and ridges in the brain.

I am very happy to receive the Young Investigators Award from EBBS! 🎉 It was a great honour and a wonderful opportunity to share my work with such an inspiring group of scientists. Many thanks to the organizers, and I look forward to the next EBBS meetings! 🙌🔬 #EBBS2025

Honored to be one of the recipients of the EBBS Young Investigators Award at the fantastic EBBS conference in Bordeaux! Huge thanks to the organizers for such an amazing event. 💐✨ #EBBS2025

The heat won’t stop the energy — science (and fans!) in full swing!

Let’s start the 51st EBBS meeting! Looking forward to great talks, ideas, and people. #EBBS2025 🧠✨

A simple action reduces high-fat diet intake and obesity in mice Diets that are high in fat cause overeating and weight gain in multiple species of animals, suggesting that high dietary fat is sufficient to cause ob…

This was a really fun project: We blocked obesity in mice by making them do a tiny bit of work for their food. www.sciencedirect.com/science/arti...

A neural mechanism for learning from delayed postingestive feedback - Nature Illness signals from the gut reactivate and strengthen flavour representations in the amygdala to support learning from delayed postingestive feedback.

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later?

Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala.

What drives our desire to eat or drink? Food or water intake is regulated by distinct circuits with specialized "thirst" and "hunger" neurons in the amygdala, a new study in mice shows. Read more: www.bi.mpg.de/news/2025-03...

I’m excited to share our publication from @dulaclab.bsky.social in @nature.com, where we illuminate the development of hypothalamic cell types involved in a broad range of functions, from social behaviors to thirst, thermoregulation, and sleep. Highlights below! 🧵

After last week publication from the lab on circuits of social isolation/satiety, today we publish a different line of research by @harriskaplan.bsky.social et al., on the development trajectories of hypothalamic POA cell types driving survival and social behavior.

Aggression experience and observation promote shared behavioral and neural changes The ability to observe the social behavior of others and use observed information to bias future action is a fundamental building block of social cognition. A foundational question is whether social o...

New year new work from the lab! We explore whether aggression experience and observation lead to similar changes in future aggression strategy. (They do!) We perform 2-color imaging across the whole social behavior network across time and track changes www.biorxiv.org/content/10.1...

Multisensory integration of social signals by a pathway from the basal amygdala to the auditory cortex in maternal mice Nowlan et al. identify a neural pathway that enables the integration of sounds and odors as female mice engage in maternal care. They report that projection neurons from the amygdala to the auditory c...

The latest paper from the Shea Lab is out today online. Here @anowlan.bsky.social shows that responses to sound in the auditory cortex merge with olfactory information via the basal amygdala. This is likely an important pathway for maternal behavior www.cell.com/current-biol...
